Subsonic Filter

[amabrok]

Thanks Matt, well you live and learn, and if red book CD can go below 20hz, it does make some sense of what I am seeing with the cone movement. However, I don't think SAM is pushing the drivers outside of their design envelope, in fact, one way of eliminating the specific issue with that track is to crank up the volume. I guess SAM is then calculating that the boost at this very low frequency would indeed be out of the drivers range, so it eliminates it.

I'm more inclined to believe that it is a factor of the SAM protective effect. I.e. A product of elimination rather than addition. And if this assumption is right then I'm not sure what the subsonic filters can offer?
